Add package.json to exports

[ambar]

webpack:

warn Package date-fns has been ignored because it contains invalid configuration. Reason: Package subpath './package.json' is not defined by "exports" in ./node_modules/date-fns/package.json

node:

node -e "require('date-fns/package.json')"

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './package.json' is not defined by "exports" in ./node_modules/date-fns/package.json

Can you please explain why

[ambar]

My assumption is some tools need to read package.json to get meta information about the project, most importantly the exports/dependencies field.
If you don't declare it, these tools can't read it.

My warning come from https://github.com/react-native-community/cli, you can close this issue because it seems unnecessary.

Appreciate it; it will go live with 3.0.2

Shipped with date-fns@3.0.2
